Deeper analysis

CVE-2024-11582 is a Stored Cross-Site Scripting (XSS) vulnerability, classified under CWE-79, in the Subscribe2 – Form, Email Subscribers & Newsletters plugin for WordPress. It affects all versions up to and including 10.43 due to insufficient input sanitization and output escaping of the ip parameter. Published on 2025-02-19, the vulnerability has a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N).

Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity, requiring no user privileges or interaction. By injecting arbitrary web scripts via the ip parameter, attackers can store malicious payloads in pages, which execute in the context of any user accessing those pages, potentially leading to low-level confidentiality and integrity impacts with a changed scope.
